Terms of Service

These terms govern your use of Nash — the service at nash-checkout.pier39.ai (powered by the open nash.v1 protocol), together with any AI shopper agent that places orders on your behalf, including the Nash MCP connector (Claude Desktop, Cowork, and other MCP clients) and the Nash Custom GPT. Nash is operated by Pier39 ("Nash", "we", "us").

By using Nash — including asking an AI agent to find a product, or completing a checkout — you agree to these terms. If you do not agree, do not use the service.

Effective date: November 2025 · Last updated: July 2026

1. What Nash does

Nash is an AI-assisted shopping and checkout service. You (or an AI agent acting for you) describe a product; Nash surfaces real products from stores in its directory and lets you complete a purchase. When you place an order, Pier39 acts as the merchant of record: you pay Pier39, and Pier39 arranges to buy the item from the origin store and have it shipped to you.

Nash is a convenience layer over other retailers. We are not the manufacturer or original retailer of the products, and we are not affiliated with or endorsed by the brands shown unless expressly stated.

2. Orders, pricing, and currency

• Prices are shown at the time you order and may change. Product prices, availability, and specifications come from third-party sources and can change without notice. The price you are charged is the price presented at checkout.
• Confirm before you pay. For some stores, prices are estimates that should be confirmed against the store at order time. Where a price is labeled estimated or converted, treat it as approximate until checkout.
• Currency. Orders may be presented and charged in USD, GBP, or EUR depending on your region. For non-US regions where a native local price is unavailable, prices may be converted from US pricing at a current exchange rate and shown as an estimate; the final local price may differ.
• Taxes and duties. Applicable sales tax or VAT may be added at checkout. For international orders, you may be responsible for import duties, customs, or other fees charged on delivery.
• Order acceptance. An order is not accepted until payment is completed and Nash confirms it. We may decline or cancel an order — for example, if the item is unavailable, mispriced, or the order appears fraudulent — and will refund any amount charged.

3. Payment

• Payments are processed by our payment provider, Stripe. By paying, you authorize the charge for the total shown (item price plus any tax/VAT and fees).
• You represent that you are authorized to use the payment method you provide.
• We do not store full card numbers; card data is handled by our PCI-compliant payment processors.

4. Fulfillment and shipping

• After payment, Pier39 arranges the purchase from the origin store and shipment to the address you provided. You are responsible for providing a complete, accurate shipping address.
• Delivery times are estimates, not guarantees, and depend on the origin store and carrier.
• If we cannot fulfill your order (item out of stock, store won't honor the order, or similar), we will cancel it and issue a full refund to your original payment method.

5. Cancellations and refunds

• You may request cancellation before an order ships; we will honor it if the origin order has not yet been placed or can still be stopped.
• Automatic refunds: if an order cannot be fulfilled within our service window, Nash may automatically refund it in full.
• Approved refunds are issued to the original payment method. Timing depends on your bank or card issuer.

6. Returns

Returns and exchanges follow the origin store's return policy. Because items ship from the origin retailer, return eligibility, windows, and conditions are set by that retailer. Contact us and we will help coordinate a return where the origin store's policy allows it.

7. Product information and third-party content

Product names, descriptions, prices, and images are sourced from third parties and are provided for identification and convenience. Images may be illustrative and may not depict the exact item, color, or configuration. We do our best to surface accurate information but do not warrant that product content is error-free, complete, or current.

8. Acceptable use

You agree not to use Nash to: place fraudulent or unauthorized orders; purchase items for unlawful resale or export in violation of applicable law; probe, disrupt, or abuse the service or its rate limits; or infringe others' rights. We may suspend or refuse service for misuse.

9. Disclaimers

Nash is provided "as is" and "as available." To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted, error-free, or that prices or availability shown are accurate.

10. Limitation of liability

To the fullest extent permitted by law, Pier39 and its affiliates will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits or data, arising out of or related to your use of Nash. Our total liability for any claim relating to an order is limited to the amount you paid for that order.

11. Indemnification

You agree to indemnify and hold harmless Pier39 and its affiliates from claims, losses, and expenses arising from your misuse of the service or violation of these terms or applicable law.

12. Changes to these terms

We may update these terms from time to time. Material changes take effect when posted at this page, with an updated "Last updated" date. Your continued use of Nash after changes take effect constitutes acceptance.

13. Governing law and disputes

These terms are governed by the laws of the State of California, USA, without regard to conflict-of-laws rules. Disputes will be resolved in the state or federal courts located in California, unless applicable consumer-protection law requires otherwise. (Jurisdiction, arbitration, and dispute-resolution terms should be confirmed with counsel for the markets you operate in, including the UK and EU.)
